Brief Summary

This study is to determine if a treatment target for a potential endovascular therapy exists in patients with an acute, spontaneous (non-traumatic) ICH.

Detailed Description

Hemorrhagic stroke caused by an intracerebral hemorrhage (ICH) is a common (roughly 15% of all strokes) and devastating disease with high rates of mortality and morbidity. The most important potentially modifiable prognostic factor after acute diagnosis of an ICH is hematoma expansion.

The investigators hypothesize that in hyperacute ICH patients a treatment target can be detected with a diagnostic, cerebral DSA. The DSA is the goldstandard for the visualization of brain vessels. A treatment target would be a vessel from which contrast media extravasates as a sign of an active bleeding. If such a target could be identified, it could lay the rationale for future trials which would evaluate if stopping the bleeding directly at the origin improves patient outcomes. The only intervention in this study is an additional diagnostic cerebral DSA. This study is to determine if a treatment target for a potential endovascular therapy exists in patients with an acute, spontaneous (non-traumatic) ICH.

Primary Outcome Measures
NameTimeMethod
Presence of a treatment target for a potential endovascular therapy (binary endpoint: yes/no)one time assessment at baseline (duration of the DSA will be 15 to 20 minutes)

Presence of a treatment target for a potential endovascular therapy (binary endpoint: yes/no). It is defined by a ruptured artery which fulfills the following two criteria:

1. Extravasate of contrast media into the surrounding tissue, and

2. Potentially reachable by a (micro-)catheter which can be used for treatment (i.e., local infusion of a procoagulant medication or (temporary) occlusion of the ruptured artery).
